Abstract

L'invention concerne un procédé et un appareil pour améliorer la performance dans des systèmes de communication. Afin de conserver les contraintes de temps réel des systèmes de communication, des intervalles temporels (404) et des signaux d'indication (406) sont utilisés dans diverses mises en œuvre pour indiquer et/ou forcer des transmissions ultérieures de données codées (410). Un signal d'indication peut comprendre, par exemple, des informations de modification de modulation pour des transmissions ultérieures. Dans diverses autres mises en œuvre, une mesure de qualité est calculée pour le canal de communication (1106) et celle-ci est utilisée pour fournir des informations de schéma de modulation modifiée (1110) devant être utilisées ultérieurement sur le canal de communication.
